and elytra ; rostrum as in the preceding ; antennse ferrugi- 

 nous ; prothorax constricted anteriorly, the side from the 

 middle gradually narrowing to the base, the disk flattish but a 

 little raised in the centre ; elytra well rounded at the side, 

 the base of each with a larger oblong tubercle, and on its 

 outer side a large velvet, blackish-brown patch, on the middle 

 another, along the suture a line of small granules, some of 

 the lateral tubercles elevated, conical, and crowned with a 

 glossy granule ; body beneath with greyish scales and setgs ; 

 first abdominal segment as large as the three nest together, 

 the sutures straight. 



Allied to the next, but, inter alia, with smaller tubercles, 

 a broader prothorax, and dark patches on elytra, &c. 



Poropterus irritus. 



P. obovatus, fuscus, opacus, supra gramilis nitidis adspersus ; pro- 

 thorace pone apicem constricto, disco bituberculato ; elytris 

 ampliato-rotundatis, tuberculis octo raajoribus instructis. Long. 

 5 1in.

Compared with the preceding this species has a narrower 

 and rougher prothorax, not so flat, and with two well-marked 

 tubercles on the disk ; the elytra have eight large rounded 

 tubercles — four at the base and four on the back posteriorly, 

 the outermost smallest, the sides and declivity with still 

 smaller tubercles, all spotted m.ore or less with glossy 

 granules, the intervals covered with a scaly matter and many 

 minute scales ; body beneath with thickish non-contiguous 

 scales, except that on the second abdominal segment they are 

 close together, that segment itself being very little shorter 

 than the first segment. 



Mr. Wallace informs me that this species is found under 

 rotten trees. As in the two preceding, the second joint of the 

 funicle is longer than the first and there is no scutellura. 



It is almost impossible to give an adequate idea of the 

 complicated sculpture of these weevils, although to the eye 

 there is no difficulty in detecting the characters differentiating 

 the numerous species of the genus, which spreads as well over 

 Australia, Tasmania, and New Guinea, but apparently not to 

 the Celebes or Borneo. They are not mentioned by Mr. 

 Tepper in his ' Common Native Insects of South Australia.'
